How to use the asphalt driveway calculator
Four quick steps turn your paved area and thickness into hot-mix tonnage, cubic yards, and an optional cost — whether you’re paving a driveway, an apron, or a small lot.
Set thickness & mix
Pick a compacted thickness — 1.5″ overlay, 2″ standard, 3″ heavy-duty — and the asphalt density (145 lb/ft³ default).
Add your paved areas
Enter each area as length × width, with a quantity for identical ones. Break odd shapes into rectangles.
Add waste & price
Set a waste/compaction factor, then an optional price per ton for a material cost estimate.
Read results & save a PDF
Get tons, cubic yards, weight, and cost, plus an area-by-area breakdown — then download a two-page takeoff.
How asphalt tonnage is calculated
Asphalt is priced by weight, so it all comes down to volume × density ÷ 2,000. Here is the exact math the calculator runs, from paved area to tons to order.
Worked example — a 50×12 driveway + 16×12 apron, 2″ compacted, 145 lb/ft³, 10% waste
Area: 600 + 192 = 792 ft²
Volume: 792 × (2/12) = 132 ft³ = 4.9 yd³
Weight: 132 × 145 = 19,140 lb = 9.6 tons
With 10% waste: 9.6 × 1.10 = 10.5 tons
Order about 10.5 tons (≈ 4.9 cubic yards) of hot-mix asphalt.
Asphalt estimating charts
Handy lookups for recommended thickness, coverage per ton, tonnage by driveway size, and density conversions. Figures assume 145 lb/ft³ compacted unless noted — mixes vary, so confirm with your plant.
| Application | Compacted thickness |
|---|---|
| Overlay / resurface | 1.5 in |
| Residential driveway | 2 in |
| Heavy vehicles / weak subgrade | 3 in |
| Parking lot — light duty | 2–2.5 in |
| Parking lot — heavy duty | 3–4 in |
All over a proper compacted aggregate base. Two-lift jobs (binder + surface) add up to the total compacted thickness.
| Thickness | Weight per ft² | Coverage per ton |
|---|---|---|
| 1 in | 12.1 lb | ~166 ft² |
| 1.5 in | 18.1 lb | ~110 ft² |
| 2 in | 24.2 lb | ~83 ft² |
| 2.5 in | 30.2 lb | ~66 ft² |
| 3 in | 36.3 lb | ~55 ft² |
Divide your square footage by the coverage figure for a quick tonnage, then add waste. Coverage drops as thickness rises.
| Paved area | Cubic yards | Tons to order |
|---|---|---|
| 400 ft² | 2.5 yd³ | 5.3 tons |
| 600 ft² | 3.7 yd³ | 8.0 tons |
| 800 ft² | 4.9 yd³ | 10.6 tons |
| 1,000 ft² | 6.2 yd³ | 13.3 tons |
| 1,500 ft² | 9.3 yd³ | 19.9 tons |
| 2,000 ft² | 12.3 yd³ | 26.6 tons |
Cubic yards shown are net (no waste). Scale linearly for other thicknesses — 3″ is 1.5× the 2″ tonnage.
| Item | Value |
|---|---|
| Compacted hot-mix density | 145–150 lb/ft³ |
| Per cubic yard | ~3,900–4,050 lb |
| 1 ton | 2,000 lb |
| 1 cubic yard | 27 ft³ |
| Volume | area × thickness (matching units) |
Density depends on the mix design. Ask your plant for the unit weight of the specific hot mix you’ll place.

7 tips for an accurate asphalt order
Asphalt is delivered hot and placed in one window, so a right-sized order matters. These habits keep your tonnage honest and your driveway lasting.
Asphalt driveway calculator FAQ
The tonnage, thickness, and coverage questions people ask most before ordering hot-mix asphalt.
Multiply the paved area by the compacted thickness and the density, divide by 2,000 for tons, then add waste.
Example: a 792 ft² driveway-plus-apron at 2″ and 145 lb/ft³ = 132 ft³ × 145 = 19,140 lb ≈ 9.6 tons, or about 10.5 tons with 10% waste.
As a shortcut, a ton covers about 80 ft² at 2″. Confirm the tonnage and mix density with your contractor or plant.
Work it as volume × density ÷ 2,000, in matching units:
1. Area = length × width (ft²)
2. Volume = area × (thickness ÷ 12) (ft³)
3. Weight = volume × density (145–150 lb/ft³)
4. Tons = weight ÷ 2,000
5. Add ~10% waste/compaction
For cubic yards, divide the cubic feet by 27. Use the compacted depth, not the loose depth before rolling.
For a typical residential driveway, 2 inches of compacted asphalt over a proper compacted aggregate base is standard. A resurface or overlay is often 1.5″, and 3″ is used for heavy vehicles or weaker subgrade.
Some jobs place asphalt in two lifts — a binder course plus a surface course — that add up to the total. Enter the combined compacted thickness.
The base underneath matters as much as the asphalt, so don’t skimp on it.
Compacted hot-mix asphalt weighs roughly 145 to 150 lb/ft³, or about 3,900–4,050 lb per cubic yard. This calculator uses 145 lb/ft³ by default.
Density varies with the mix design and aggregate, so dense-graded mixes sit at the higher end.
Because asphalt is priced by the ton, this unit weight is what turns your paved volume into a tonnage. Ask your plant for the density of your specific mix.
At 2″ compacted and 145 lb/ft³, one ton covers about 80 ft². Thinner layers stretch a ton further:
• 1 in: ~165 ft²/ton • 1.5 in: ~110 ft²/ton
• 2 in: ~80 ft²/ton • 3 in: ~55 ft²/ton
Divide your total square footage by the coverage figure for your thickness to get a quick tonnage, then add waste.
It depends on size, but here are rough figures at 2″ compacted with 10% waste:
• Small (400 ft²): about 5.3 tons
• One-car (~600 ft²): about 8 tons
• Two-car (~800 ft²): about 10.6 tons
• Large (~1,000 ft²): about 13.3 tons
Break your driveway, apron, and any turnaround into rectangles, add them up, and apply the coverage for your thickness.
Almost always. Asphalt is a wearing surface, not a structural slab — it needs a compacted aggregate base beneath it to carry load and drain water. A typical residential base is several inches of compacted crushed stone over a firm, well-drained subgrade.
This calculator estimates the asphalt (hot mix) only. The base gravel, grading, and compaction are separate materials and steps — and getting them right is what keeps a driveway from cracking and rutting.
Plan and price the base in addition to the asphalt.
A 10% allowance is common. It covers spread and handling loss, thicker spots at edges and transitions, and normal compaction variance.
Asphalt is delivered hot and has to be placed and rolled in one window, so running short mid-job is a real problem — a cold joint or a second small load both hurt quality and cost.
Rounding the tonnage up is cheap insurance. Use a little less for a small simple area, a little more for cut-up or hand-worked ones.
Estimating Notice: Actual asphalt tonnage varies with the mix design, compacted density, layer thickness, spread and handling loss, and how the area is measured. This calculator provides volume- and weight-based tonnage, cubic yards, and an optional material cost from your input — density and price are regional and mix-specific, so always confirm them with your paving contractor or hot-mix plant. It estimates the asphalt (hot mix) only; the aggregate base course, grading, compaction, and labor are separate and not included. Verify all quantities and pricing before ordering.
